Shows from today back to when the executive branch didn't exist.
Today, there is an executive branch. This consists of the president and they have to enforce the laws passed.
The executive branch is outlined in the 2nd article of the Constitution. It shows what this branch specifically needs to do. It had been created 1787. In section 3 is states that they must enforce all laws no matter what their constitution opinion is. Since this article had been created, the executive branch has been able to enforce laws.
This had all been to show leadership. But in the Executive branch, you need to vote for who is the president. Then they have duties to fulfill. For example, enforce the laws.
Before the executive branch had existed, there had been no leader to enforce the laws. The people created the first Congress in North America did not want the government turn into a tyranny like what had happened with the British.
